Description

Technical Field

[0001] This utility model relates to the field of children's fences, specifically a children's fence connector. Background Technology

[0002] Children's playpens, also known as play fences, safety fences, or child safety barriers, primarily serve to free up mothers' hands and provide a safe and comfortable environment for babies aged 6 months to 3 years to learn to walk and play. Using children's playpens helps cultivate a baby's independence, thinking ability, and concentration, while also providing an excellent activity space for developing their physical coordination.

[0003] Existing children's fences generally consist of a gate, a play area, and individual fence panels, which are connected by slotted joints. Stability is mainly achieved through the splicing of four sides, while suction cups at the bottom help prevent slipping.

[0004] However, existing children's fences cannot be folded well, and due to the limitations of the connectors, the angle between adjacent fence panels is relatively limited. They can generally only be adjusted into a quadrilateral and cannot be expanded into a hexagon or octagon. This makes the use of children's fences quite restrictive, as they cannot be arranged and adjusted according to the layout of the home, resulting in poor flexibility. They also cannot help develop children's spatial thinking and have poor functionality. Utility Model Content

[0005] The purpose of this utility model is to provide a children's fence connector that can adjust the angle between adjacent fence panels by rotating the connector and fix the angle position, so that the fence is not limited to a quadrilateral shape, but can be flexibly adjusted according to the layout of use, and can also exercise children's spatial thinking through fences of various shapes, thus improving functionality.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A child fence connector includes a first connector and a second connector, wherein the first connector and the second connector are rotatably connected at their near ends, and the far ends of the first connector and the second connector are respectively connected to the fence.

[0008] Both the first connector and the second connector have a locking hole inside their respective ends close to each other. The locking hole has a locking tooth groove, which is distributed in both the first connector and the second connector. A locking gear that can mesh with the locking tooth groove is also slidably provided in the locking hole.

[0009] A button is slidably inserted into the first connector, and a spring adjustment mechanism linked to the button is provided in the lock hole. By pressing the button, the spring adjustment mechanism is triggered, causing the locking gear to slide and change position in the lock hole and then fix its position. This positions the locking gear in a position where it simultaneously engages with the locking teeth of the first and second connectors, thereby locking the angle of the connector; or the locking gear can be positioned in a position where it engages with the locking teeth of the second connector alone, allowing the first connector to be rotated to adjust the connection angle.

[0010] Furthermore, the spring adjustment mechanism includes multiple guide blocks disposed on the inner wall of the lock hole of the first connector. A switching gear and an adjusting gear are also slidably disposed in the lock hole of the first connector. The outer sides of the switching gear and the adjusting gear are provided with guide grooves that slide and engage with the multiple guide blocks. The top of the adjusting gear is provided with multiple slots. The surface of the slots and the bottom of the guide blocks are both inclined surfaces, so that the adjusting gear can rotate under the contact and engagement of the slots and the inclined surfaces at the bottom of the guide blocks. The spring adjustment mechanism also includes a spring disposed in the second connector and located at the bottom of the locking gear.

[0011] Furthermore, the second connector is provided with a limiting rod that passes through the spring, locking gear, adjusting gear, and switching gear respectively.

[0012] Furthermore, the top outer ring of the first connector is provided with a scale, and the second connector is provided with an indicator mark.

[0013] Furthermore, the guide block is located at the top of the locking tooth groove, and the outer diameter of the adjusting gear and the switching gear is not greater than the minimum inner diameter of the locking tooth groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This patent connects adjacent fence panels using a first connector and a second connector, which are rotatably connected. A spring adjustment mechanism is triggered by pressing a button, causing a locking gear to slide and change position within a lock hole before fixing. This positions the locking gear simultaneously with the locking teeth of both the first and second connectors, locking the angle of the connector. Alternatively, the locking gear can be positioned to engage with the locking teeth of the second connector alone, allowing the first connector to be rotated to adjust the connection angle. Both states are operated by pressing a button. A 360° angle adjustment is possible between the two connectors. By rotating and fixing the angle between the first and second connectors, the angle between two adjacent fence panels can be adjusted. This allows for multiple configurations of the children's fence, such as quadrilaterals, hexagons, and octagons, and facilitates folding for easy storage. The fence shape can be flexibly adjusted according to the layout, and the various shapes of the fence can help develop children's spatial reasoning, resulting in enhanced functionality.

[0023] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0024] The present invention relates to a children's fence connector. The main structure includes a first connector 1 and a second connector 2. The ends of the first connector 1 and the second connector 2 that are close to each other are cylindrical and rotatably connected. The ends of the first connector 1 and the second connector 2 that are far from each other are clamping structures and are respectively connected to the fence. This allows the first connector 1 and the second connector 2 to serve as components for connecting two adjacent fence panels. The angle between the two adjacent fence panels can be adjusted by rotating the first connector 1 and the second connector 2.

[0025] Both the first connector 1 and the second connector 2 have a locking hole 3 inside their respective ends close to each other. The locking hole 3 has a locking tooth groove 4 inside it. The locking tooth groove 4 is distributed in both the first connector 1 and the second connector 2 and is located in the portion close to the first connector 1 and the second connector 2, so that the locking gear 5 can slide back and forth between the first connector 1 and the second connector 1 along the locking tooth groove 4. The locking hole 3 also has a locking gear 5 that can mesh with the locking tooth groove 4 and can slide with the locking tooth groove 4. The number of teeth of the locking gear 5 is the same as the number of grooves of the locking tooth groove 4.

[0026] A button 6 is slidably inserted into the first connector 1. The bottom of the button 6 has a pressure rod located in the lock hole. The lock hole 3 is equipped with a spring adjustment mechanism that is linked to the button 6. By pressing the button 6, the spring adjustment mechanism is triggered, causing the locking gear 5 to slide and change position in the lock hole 3 and then fix its position. This positions the locking gear 5 in a position that simultaneously engages with the locking tooth groove 4 of the first connector 1 and the second connector 2, thereby locking the angle of the connector. This position can be achieved by setting an appropriate thickness for the adjusting gear 9 and the switching gear 8. Alternatively, the locking gear 5 can be positioned to engage with the locking tooth groove 4 of the second connector 2 alone, thereby rotating the first connector 1 to adjust the connection angle. Both states of the locking gear 5 are achieved by pressing the button 6, and pressing the button 6 can also switch the state of the locking gear 5, thereby adjusting the angle between the two connectors. This allows for the adjustment of the angle between two adjacent fence pieces connected by the connector, enabling multiple shape conversions such as quadrilateral, hexagonal, and octagonal after the children's fence is combined.

[0027] Preferably, the spring adjusting mechanism includes multiple guide blocks 7 disposed on the inner wall of the locking hole 3 of the first connector 1. The guide blocks 7 are located at the top of the locking tooth groove 4. A switching gear 8 and an adjusting gear 9 are also slidably disposed in the locking hole 3 of the first connector 1. The outer diameter of the adjusting gear 9 and the switching gear 8 is not greater than the minimum inner diameter of the locking tooth groove 4, ensuring that the adjusting gear 9 and the switching gear 8 slide within the locking hole 3. The outer sides of the switching gear 8 and the adjusting gear 9 are provided with guide grooves 10 that slide and engage with the multiple guide blocks 7, allowing the adjusting gear 9 and the switching gear 8 to slide along the guide blocks 7. The top of the adjusting gear 9 is provided with multiple slots 11. The surface of the slots 11 and the bottom of the guide blocks 7 are both inclined surfaces, making the multiple slots 11 serrated at the top of the adjusting gear 9. This allows the adjusting gear 9 to rotate under the contact engagement of the slots 11 and the inclined surfaces at the bottom of the guide blocks 7. The multiple slots 11 and the multiple guide grooves 10 on the adjusting gear 9 are also connected. The staggered arrangement allows the guide block 7 to sequentially align with the slot 11 and guide groove 10 after the adjusting gear 9 rotates. This allows the bottom of the guide block 7 to engage with the top of the slot 11 after the adjusting gear 9 rotates, and then slides into the guide groove 10 of the adjusting gear 9. This allows the height of the adjusting gear 9 to be adjusted within the locking hole 3. The spring adjustment mechanism also includes a spring 12 located within the second connecting member 2 and at the bottom of the locking gear 5. The elastic force of the spring 12, combined with the engagement between the slot 11 and the bottom of the guide block 7, enables the locking gear 5 to slide up and down and maintain its position. The overall spring adjustment mechanism of this patent can be referenced from the existing ballpoint pen structure where pressing exposes the pen tip and pressing again retracts the pen tip. Those skilled in the art can refer to the existing ballpoint pen pressing structure and combine it with the description in this patent specification to clearly and completely understand the structural composition of the spring adjustment mechanism and the working principle of the cooperation between the components.

[0028] Preferably, the second connecting member 2 is provided with a limiting rod 13 that passes through the spring 12, the locking gear 5, the adjusting gear 9, and the switching gear 8 respectively. The limiting rod 13 further limits the sliding direction of the locking gear 5, the adjusting gear 9, and the switching gear 8, as well as the contraction direction of the spring 12.

[0029] Preferably, the top outer ring of the first connector 1 is provided with a scale 14, and the second connector 2 is provided with an indicator mark 15, which helps to confirm the size of the adjustment angle between two adjacent fence panels.

[0030] Instructions for use:

[0031] Initially, the locking gear 9 is in a position where it is simultaneously engaged with the locking tooth groove 4 of the first connecting member 1 and the second connecting member 2;

[0032] 1. Press button 6 and release it to push switch gear 8 to move adjustment gear 9 down. When adjustment gear 9 moves down to the top slot 10 and contacts the bottom end of guide block 7, the adjustment gear 9 rotates under the action of slot 11 and the inclined surface at the bottom end of guide block 7, so that the bottom end of guide block 7 is locked in slot 11 and the spring 12 is compressed. Under the reverse thrust of spring 12, guide block 7 is firmly locked in slot 11, thereby fixing adjustment gear 9 in a lower position. At this time, adjustment gear 9 pushes locking gear 5 into the locking tooth groove 4 of second connector 2. At this time, first connector 1 can be rotated to adjust the angle between the two connectors.

[0033] 2. Press button 6 again and release it to push switch gear 8, which will press down adjustment gear 9 again. Under the action of slot 11 and the inclined surface at the bottom of guide block 7, adjustment gear 9 will rotate again. After rotating again, guide block 7 will correspond to guide groove 10 of adjustment gear 9, so that adjustment gear 9 will move up and reset under the push of spring 12. Locking gear 5 will also move up under the push of spring 12 and finally return to the position where it meshes with the locking tooth groove 4 of first connector 1 and second connector 2. At this time, the angle shape of the connector can be locked.

[0034] This patent allows for angle locking and adjustment between the first connector 1 and the second connector 2 by pressing button 6. By rotating and adjusting the angle between the first connector 1 and the second connector 2 and fixing it, the angle between two adjacent fence pieces can be adjusted. This enables multiple shape transformations of the combined children's fence, such as quadrilateral, hexagonal, and octagonal, as well as convenient folding for storage. It allows for flexible adjustment of the fence shape according to the usage layout and also helps to develop children's spatial thinking through fences of various shapes, resulting in better functionality.
